Mr Browder will reveal results of a six-year long investigation into the money laundering and proceeds of corruption exposed by Sergei Magnitsky, which led to Magnitsky’s arrest, torture and murder in Russian police custody at the age of 37.

The information will include detailed descriptions of luxury purchases in London and surrounding counties totalling US$30 million connected to the money laundering network uncovered thanks to Sergei Magnitsky.

This investigation was assisted by Alexander Perepilichnyy, a Russian whistleblower who came forward after Sergei Magnitsky’s death and provided bank statements leading to more than US$15 million being frozen by Swiss Prosecutor General in a separate Swiss money laundering investigation. Perepilichnyy died in November 2012 in suspicious circumstances in front of his home in Weybridge, Surrey at the age of 44.

The investigation into the Magnitsky case has recently revealed a connection of the proceeds from the crime Sergei Magnitsky uncovered to the ‘Panama Papers,’ and specifically to Sergei Roldugin, President Putin’s long-time friend and cellist.
